1095 won't show up in non-Mach gdb's!
1096 * thread.c: change name of static function "thread_switch" to
1097 "switch_to_thread", to avoid conflict with Mach global symbol;

1254 to _filtered forms to make output appear in GUIs. Replace all
1255 uses of SERIAL_READCHAR with readchar, which has better error
1257 * (e7000_parse_device): Add prototype.
1258 (readchar): Improve doc. Handle random serial errors.
1259 (expect): Disable notice_quit code. It's busted. Remove

1261 remote_debug echoing. That's handled in readchar as well.
1262 (e7000_parse_device): Remove serial_flag arg. It's not
1264 (e7000_open): Split into two pieces. Second part is
1265 e7000_start_remote, and is error protected. Now, when we connect
1266 to the target, we setup the initial frame and registers so that
1267 the user gets an immediate indication of where the target is.
1268 (gch): Remove debug output. That's handled by readchar.
1269 (e7000_read_inferior_memory): Handle errors better.
1270 (_initialize_remote_e7000): Get rid of `<xxx>' things from
1271 command names. They show up when doing completion and confuse

1347 (uninstall): Transform name.
1349 Mon Apr 14 17:06:27 1997 Mark Alexander <marka@cygnus.com>

1366 since gcc automatically includes it
1368 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1370 * procfs.c: Substantial (but incomplete) changes to support
1371 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1372 struct now has substructs like struct flt_ctl instead of
1373 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1374 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1375 still have the structs and multiple fds, but don't use the
1376 entire struct and the four fds all point to the same thing.
1377 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1378 procfs with reads/writes or use ioctl instead. We use
1379 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1380 multiple fds or not. PROC_NAME_FMT is split out into
1381 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1382 STATUS_PROC_NAME_FMT.
1384 (procfs_notice_signals): now a necessary wrapper around
1385 (notice_signals): which are the new guts for noticing signals
1386 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1387 determine whether or not to attempt to open the ctl_fd.
1388 (procfs_read_status): new local function, reads procfs status
1389 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1390 (procfs_write_pckill): new local function, writes a PCKILL
1391 (unconditionally_kill_inferior): remove signo since we now
1392 just call procfs_write_pckill().
1393 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1394 (proc_iterate_over_mappings): the whole function is ifdefed
1395 on UNIXWARE to keep things readable.
1397 Expanded the syscall_table to include new potential sysv4.2mp
1398 members. Note that all ifdefs of UNIXWARE should be eliminated
1399 if possible or renamed to describe what's being selected for a
1400 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1401 IRIX specific code now also checks it's not UNIXWARE.
1403 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1404 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
1405 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
1406 "/debug/%d" as PROC_NAME_FMT used to be
1408 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
1410 * mn10300-tdep.c: Almost completely rewritten based on mn10200
1412 * config/mn10300/tm-mn10300.h: Likewise.
1414 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
1416 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1417 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1418 lousy out-of-date clone of remote.c.
1420 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
1422 * remote.c: Fix problems realized while showering.
1423 * (hexnumlen): Add prototype. Use max, not min.
1424 * (remote_write_bytes remote_read_bytes): Fix max packet size
1425 calculations to properly account for packet overhead. Also handle
1426 (probably rare) case where remote_register_buf_size isn't set.
1428 * remote.c: Fix doc for `C' and `S' commands to indicate full
1430 * (remote_ops extended_remote_ops remote_desc remote_write_size):
1432 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
1433 Record size of response to fetch registers command, use this to
1434 limit size of memory read and write commands.
1435 * (push_remote_target): New function to make it possible to have
1436 another target switch to the remote target.
1437 * target.h: Add prototype for push_remote_target.
1438 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
1439 for hosts which default to unsigned chars (such as SGI's).
1440 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
1441 handled automatically in remote.c.
1443 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1445 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1446 find_pc_sect_function(), find_pc_sect_partial_function(): new
1447 functions for debugging overlays; pc without section is ambiguous.
1448 * breakpoint.[ch]: add section pointer to breakpoint struct;
1449 add section argument to check_duplicates(); check section as well
1450 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1451 breakpoint_thread_match(), bpstat_stop_status()];
1452 add section argument to describe_other_breakpoints();
1453 use INIT_SAL() macro to zero-out new sal structures;
1454 make resolve_sal_pc() fix up the sal's section as well as its pc;
1455 match on section + pc in clear_command() and delete_breakpoint();
1456 account for overlay sections in insert_breakpoints(),
1457 remove_breakpoint() and breakpoint_re_set_one();
1458 all this to support overlays where a PC is not unique.
1459 * exec.c: change xfer_memory() to handle overlay sections.
1460 * findvar.c: change read_var_value() to handle overlay sections.
1461 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
1462 * infcmd.c: jump_command() warns against jumping into an overlay
1463 that's not in memory. Also use INIT_SAL() to initialize sals.
1464 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1465 overlay state information; Also use INIT_SAL() to init sals.
1466 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1467 * m32r-stub.c: mask exit value down to 8 bits; screen out any

1484 translating between VMA and LMA address ranges, determining if an
1485 overlay section is mapped, etc. Add several user commands for
1486 overlay debugging. Add support for a "generic" form of automatically
1487 reading overlay mapping info from the inferior (based on the default
1488 (simple) overlay manager which Cygnus provides as an example).
1489 * symtab.[ch]: add functions find_pc_sect_symtab(),
1490 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1491 for lookup; modify lookup_symbol and decode_line_1() to use them;
